 ## Unreleased / Draft
 
+## [1.2.0] - 2021-05-31
+
+### Added
+
+- **New extensions:**
+    - [Commercial Data Extension](./extensions/commercial-data/README.md)
+    - [Federation Extension](./extensions/federation/README.md)
+- `GET /`: New Relation types: [#404](https://github.com/Open-EO/openeo-api/issues/404)
+  - `create-form` to link to the registration page
+  - `recovery-form` to link to the credentials recovery page.
+- `GET /file_formats`: Add `pointcloud` to the `gis_data_types`. [#475](https://github.com/Open-EO/openeo-api/issues/475)
+- `GET /me`: New Relation types `alternate` and `related` for user-specific external pages. [#404](https://github.com/Open-EO/openeo-api/issues/404)
+- `GET /credentials/oidc`: Allow `authorization_code` and `urn:ietf:params:oauth:grant-type:device_code` (both without PKCE) as grants for `default_clients`. [#410](https://github.com/Open-EO/openeo-api/issues/410)
+- `GET /jobs` and `GET /jobs/{job_id}`: Added a links property that can for example link to results and logs. [#453](https://github.com/Open-EO/openeo-api/issues/453)
+- `GET /jobs/{job_id}/results`:
+  - Recommendation to add a link with relation type `canonical` which points to a signed URL with the same content as the response. [#397](https://github.com/Open-EO/openeo-api/issues/397)
+  - Added metadata field `openeo:status` to indicate the job status (and whether the result is complete or not).
+  - Added parameter `partial` to allow retrieving incomplete results, which must also add the new property `openeo:status` to the metadata. [#430](https://github.com/Open-EO/openeo-api/issues/430)
+- `GET /jobs/{job_id}/logs`, `GET /services/{service_id}/logs`: Added `level` parameter to requests to set the minimum log level returned by the response. [#485](https://github.com/Open-EO/openeo-api/issues/485)
+- Added property `log_level` to secondary web service, batch job and synchronous processing endpoints to indicate the minimum severity level that should be stored for logs. [#329](https://github.com/Open-EO/openeo-api/issues/329)
+- `GET /jobs/{job_id}/logs`, `GET /services/{service_id}/logs` and `POST /result`: Added `level` property in responses to reflect the minimum log level that may appear in the response. [#329](https://github.com/Open-EO/openeo-api/issues/329)
+- Recommendation to add media types and titles to links for a better user experience.
+- Allow the relation type `canonical` to be used generally for (shared) resources (e.g. UDPs or batch jobs) without requiring Bearer authentication. [#405](https://github.com/Open-EO/openeo-api/issues/405)
+- Recommendation for UDF runtime names. [#409](https://github.com/Open-EO/openeo-api/issues/409)
+- Processes: Added `dimensions` schema for subtype `datacube`
+- Collections: Added `geometry` dimension type to `cube:dimensions`
+- New endpoint for metadata filters (queryables): `/collections/{collection_id}/queryables`. Also adds a new rel type to the collection links. [#396](https://github.com/Open-EO/openeo-api/issues/396)
+
+### Changed
+
+- Updated STAC specification examples and references to v1.0.0, please see the [STAC changelog](https://github.com/radiantearth/stac-spec/blob/master/CHANGELOG.md) for all changes between 0.9 and 1.0.
+- `cube:dimensions`: `reference_system` is allowed to be PROJJSON, too. 
+- Relaxed requirement that unsupported endpoints must return HTTP status code 501. Instead also HTTP status code 404 can be used (and is regularly used in practice). [#415](https://github.com/Open-EO/openeo-api/issues/415)
+- Minimum value for `costs` and `budget` is 0.
+- `GET /jobs/{job_id}/estimate`: If a batch job can't be estimated reliably, a `EstimateComplexity` error should be returned. [#443](https://github.com/Open-EO/openeo-api/issues/443)
+- The `/conformance` endpoint is now generally used for OGC APIs, STAC API and openEO. `conformsTo` is also exposed in `GET /` for STAC APIs. The openEO API and all extensions got individual conformance classes. [#186](https://github.com/Open-EO/openeo-api/issues/186)
+
+### Fixed
+
+- Explicitly mention the use of HTTP content negotiation
+- Clarify that the default charset is UTF-8 [#462](https://github.com/Open-EO/openeo-api/issues/462)
+- Fixed inconsistencies in errors.json: removed `ProcessGraphIdDoesntMatch`, clarified `ProcessGraphMissing`, added `ProcessInvalid` and `ProcessGraphInvalid`. [#394](https://github.com/Open-EO/openeo-api/issues/394), [#395](https://github.com/Open-EO/openeo-api/issues/395), [#401](https://github.com/Open-EO/openeo-api/issues/401)
+- Fixed the default value for the version number in the API url (`v1.0` -> `v1`) and improved the description for API versioning. [#393](https://github.com/Open-EO/openeo-api/issues/393)
+- Fixed the Collection example to use `gsd` instead of `eo:gsd`. [#399](https://github.com/Open-EO/openeo-api/issues/399)
+- Clarify use of `user_id`. [#404](https://github.com/Open-EO/openeo-api/issues/404)
+- Clarify that the relation type `version-history` should include `/.well-known/openeo` in the URL.
+- Clarify that clients should (re-)request capabilities and discovery endpoints with token if available and supported. [#416](https://github.com/Open-EO/openeo-api/issues/416)
+- Clarify the fields `plan` (for processing requests) and `billing_plan` (in `GET /` and `GET /me`). [#425](https://github.com/Open-EO/openeo-api/issues/425) [#426](https://github.com/Open-EO/openeo-api/issues/426)
+- Clarified ambiguous batch job status changes.
+- Reflect that the `debug` process has been renamed to `inspect`.
+- Clarified uniqueness constraints for identifiers. [#449](https://github.com/Open-EO/openeo-api/issues/449) [#454](https://github.com/Open-EO/openeo-api/issues/454)
+- Clarified schematically the applicability of JSON Schema extensions (`parameters`, `returns`, `dimensions`) and their relation to the subtypes
+- `GET /`: Removed the superfluous default value for `currency`. [#423](https://github.com/Open-EO/openeo-api/issues/423)
+- `GET /credentials/oidc`: Clarify that clients may add additional scopes
+- `GET /me`: Clarify the behavior of the field `budget`.
+- `GET /jobs/{job_id}/logs`, `GET /services/{service_id}/logs` and `POST /result`: Clarified the formatting of the `message` property. [#455](https://github.com/Open-EO/openeo-api/issues/455)
+- `GET /jobs/{job_id}/estimate`: Don't require that the costs are the upper limit. Services may specify the costs more freely depending on their terms of service.
+- `GET /services` and `GET /services/{service_id}`: Clarify that `enabled` is required by removing the default value. [#473](https://github.com/Open-EO/openeo-api/issues/473)
+- Several appearances of `nullable` were clarified according to the lint report by Spectral
+- Clarify how the well-known document works [#460](https://github.com/Open-EO/openeo-api/issues/460)
+- Clarify handling of JSON Schema versions

 ## Repository
 
 This repository contains a set of files formally describing the openEO API, each with a human-readable and easily browseable version:
 
 * [openapi.yaml](openapi.yaml) provides the [OpenAPI](https://www.openapis.org/) 3.0 definition of the openEO API. See the table above for human-readable versions of the OpenAPI definition.
 * [errors.json](errors.json) is a list of potential global error codes and messages, excluding specific exceptions separately available for each process.
 * The [assets](assets/) folder contains some useful additional files such as examples or schemas. All of these are non-binding additions. The source of truth are the top-level specification files.
+* The [extensions](extensions/) folder contains extensions to the openEO API.
+
+# Development
+
+The `draft` branch is the latest version and is the one to create Pull Requests against.
+
+For development some tools can be used:
+
+1. Install [node and npm](https://nodejs.org) - should run with any recent version
+2. Run `npm install` in this folder to install the dependencies
+3. Run the linter for the OpenAPI file with `npm test`. This will lint the files and check against some best-practices. It uses `spectral` in the background.
+4. To show the files nicely formatted in a web browser, run `npm start`. It starts a server and opens the API specification rendered with ReDoc in a web browser.
+5. To create a static HTML page (e.g. for hosting it on GitHub Pages), you can run `npm run build` and it will create a `redoc.html` in this folder.
